TO ALL WHO-.1I -I'l M-AYCONCEBN:

Be it known that I, JOHN CASE, of Athens, in the county of Athens, and State of Ohio, have invented a new' :1nd useful Improvement in Angular Shaft-Coupling; and'ldo hereby declare that the following is a full, elcar, and exact description thereof, which will enable others skilled inthe art to make and use the some, reference being had to the accompanying drawings, forming part of this specification; i

Figure 1 is :t top view of two shafts connected by my improved coupling.

Figure 2 is n detail sectional view of the sarde, taken through' the line :v x, iig` 1.

Similar letters ot' reference indicate corresponding parts.

My inventionhns for its object to furnish 'an improved coupling or gearing for connecting shafts .to each 'other at any desired angle, which shell he so constructed and arranged as to,securely couple the shafts, run

with 155s mise and 'with 1m #vif-.fion .than the,ordinari-wherein carin Vmid xyln'ahshall et besmetting .re eine', i g a r r q less materiel for its construction; and it consists in the combination 4of the oblong fremen'having cogs or teeth formed upon the ends of their forward sides, and the pivoted connectingbars, with each other, und with,the adjacent ends offthe shafts, as hereinafter more fully' described. i v i i A and B represent the shafts to be coupled. C are the coupling-frames, which are' mede ot'l on oblong for-m. c are segments of cog or gear-wheels, which .are formed solidly-upon or nresccurcly attached te the forward side of the frames C nt their ends, as shown in figs. 1 und 2. The frentes are connected toand held in. gear with each other by the hers D, the ends of which are pivoted to the ends of the said frames, as shown in the drawings. By this construction the teeth formed upon Athe said frames C will be always in gear witheach other, into whatever position `the szlid'frnm'es may be turned. are bells, into or. through which the ends of the shafts A and B poss, and which nre secured to thc said shafts, to furnish secure and convenient bearings' for the frame C. li' are set-screws, which pnss-through holes i-n the sides of the vframes C, and are screwed into the opposite sides of vthe halls E, so that their inner ends may press ngeinst the opposite sides of the ends of the shnft's A and B', as shown in figs. 1 and 2, the outerpor projecting ports of the seid screws forming .the pivotingpins, upon which the seid frames C work. By this construction the shafts may be coupled at :tn-y desired angle,A and, 4the pressure being. 'equally diyided bctweenrthe coge or teeth' upon the two ends ofthe frames C, said frames 4 u v and teethneed not he mode so strong, :rnd consequently do not require so much material for their constructlon,

asetheririsc would be the ces I claim as new, and desire to secure -by Letters Pzitent- 'Ihe combination of the oblong frames C, having cogs or teeth, c', formed upon the ends of their forward sides, and the pivotedconnecting-bers D, with eachother, and with the ends of the connected or coupled shafts, substantially as 'herein shown and described, alnd for the purpose set forth. i
